I want to build my own dolly and I have no access to a Seitech dolly right now. Can anyone tell me what is the size of the tubing, and the thickness of the wall? I plan to use the Vosper plan that you can see on the Dr Laser site but in aluminium. Did anyone try it? Do you have any comment?

Your time is worth whatever someone is willing to pay you on that day. If it's a day where you have no work it would seem to me that your time that day is worth 0.TheBoathouse said:1 day to build it. This is my point exactly. My time is worth at least $50 per hour x 8 hours = $400 + $150 for materials = $550...

Lets make some calculations Mr. Fox:
The price to hire me is not US$ 50 "brutto", it´s "netto" 10 Euro, without expenses of course.
By the way, 1 Euro is about 1,25 to 1,3 US-$....
It is not correct to add the social-cost and tax to that wages during a freetime-work, I think. If I work for a job during that time that I would save for not building my own dolly, I also do only see the netto-wage in my wallet to earn that money for paying the professional build dolly.
So, lets make the things more in details:
It needed more than the official price which is here in GER at about 299 Euro for the TRD and over 330 Euro for the Seitech to get that dolly. I spent 1 h to get that dolly (time for internet-demand and payment at the German-Bank). Cost of the transport:via Postal-service DHL in Germany to transport a big box like for the TRD/Seitech is about 30 Euro. This means for a TRD over all: 339 Euro brutto I have to take out of my wallet.
Time to work and earn money to buy that professional-manufactured-dolly: 8 h.
This has the trivial restriction: I have to have such a job. [In reallity: I have not such a job, I´m employee, that get´s every month the same money, no matter if I work more or less than that time that is contracted with my boss.]
But lets imagine I have an "additional-job", where I get that extra money (f.e.: washing cars, cutting the grass in the neighbours gardens for 10 Euro each hour, which is far to much for that work here). So, 80 Euro I can earn during that time I do not construct a home-made-dolly – but never 8 x 50$=400$ (or 8 x (50/1,25)= 320 Euro).
This means, the professional dolly would cost me 339-80= 259 Euro.
Now the other side:
8h to get the goods for the dolly and construct it. 1h to get the construction-plans and understand them and make a list for the home-depot store.
This is 9h à 10 Euro = 90 Euro.
The price for the goods for a homemade dolly is about 150 Euro here (aluminium tubes, stainless-steel-bolts/nuts/washers, stainless-steel-plates for the connection of the tubes, 2 axles, 1 foam-tube 2 air-pumped wheels of a wheelbarrow, etc.-etc...).
Transport-cost from home-depot to home are about 10 Euro.
This is together: 90+150+10= 250 Euro for the homemade dolly.
Can I say: I saved about 9 Euro with creating my own Laser-dolly?
(- Or with out looking to that money/time-calculations: 339-160= 179 Euro?)
No, I think, this would not be correct. Why? Well, the dolly has warranty and in my opinion, a professional-manufactured dolly is easier to dismantle (in reason of professional conection-parts that I can´t constuct in that quality in that time) and has a better quality of (alu-)material.
This also was nearly my quick-calculation on that day (20h before take of into holidays) the axle of home-made-PP-plastic-tube-dolly-“à la Mr. John-DE” broke down.
But, when I´m at home, in my freetime, in my opinion it is not correct, to measure all with economic scales. What will cost “5 min cleaning my tooth” etc.? Would it be correct to say: “making a breakfast at home is more expensive than at an US-fastfood-restaurant, so in future I should never eat at home?” I think, this goes to far.
I understand the Laser-store-owners in the massive economical pressures from the Out-of-the-box-boat-builders to sell more things to the sailors, but it´s every customers own decision whether she/he goes to a store and get a thing or build it her/his own. And I´m sure, Francois will do the right thing for himself.
P.S. My PP-Plastic-tube-dolly was reconstructed later on. But in the opposite to Canada, until today, we have no suitable PVC-Tubes and suitable ABS-Cement for it here in GER - what a luck for the owners of the GER-Laser-stores ....;-)

@Steven: I checked again the link to TRD ("RF TR-2001-racing"-dolly) in that reply. You are right, take http://www.trd-bcn.com/. My Browser (I.E. 6) corrects that mistake (I forgot “http://www.”) automatically, but maybe other browser not, Sorry for that.

That would be grand! As well as a picture?Crooked Beat said:Perhaps I should post the design?
For an aluminium-dolly with rectangular-diameter-beams diameter 3cm x 7 cm and thickness of 0,2 cm will work. Length for the axle-beam: about 130 cm, lenght-beam: about 220 cm, lenght of the "_/"-part is about 60cm.TheBoathouse said:Its 1 1/2" square by 1/8" thick (no I am not going to convert it to metric for you ...
Hello. I can’t get that zip file to open. Would you mind resisting it? Thank you.I have been having trouble loading up documents. Hopefully you should see a zip file of the jpg drawing. I may have a photo of the dolly on the laser upside down on the car. Has worked for many years.
I just noticed in my original post that I said I bolted it together. That was what I originally did. But I had a friend with a MIG welder and we welded it up. Bolts held fine. While you are at Home Depot, get your top rails and then go over to the electrical aisle. Look for the pipe benders. Put your top rails in the bender and bend your rails! No need to buy a pipe bender! I also would bend one end of another top rail to use as your (removable)handle. I should also add that the front pipe is a corner post - which is of a larger diameter.
