From 3D drawing to Rotisserie

I know I'm not the first one to build this thing, but maybe someone can use the information. My goal with this rotisserie was to use similar size material and reduce cost without sacrificing integrity. I started by referencing Tommy B's Rotisserie and then I then built a 3D drawing. You can see the drawing and download it here. All said and done, I spent $110 including hardware. The end product looks great as not much was changed from the original design. The only thing I haven't done is drill the mounting holes for the tub. I have the tub on the frame for body mount work.



I used 1/2-13 bolts on all hardware. I also used "plain" non coated nuts and welded em' on














I welded the casters on because I'm lazy and didn't want to drill 16 holes. 3 1/2" caster from HF

 

nicely done!

if i could just get up to the steel yard, maybe i could start on mine!!

looks great, and thanks for the dwgs!

how do we open them up? i dont know what a .skp is

 

You will need to download Google SketchUp, it's free.

 

Different screen shot for Philip-TX

 

nice,

thanks

 

cool! thanks!

maybe i could play with it and make a dwg of parts of my own...

again, VERY cool... thanks!

what material did you use...?

". My goal with this rotisserie was to use similar size material and reduce cost without sacrificing integrity."

 

Well done, PieLut. The rotisserie definitely makes the body work go easier and faster. I even painted my tub while it was on the rotisserie.

 

Material list for TexasBlues

2 sticks (40 feet) of 1-3/4 x 1-3/4 x 0.090 wall

3 feet of 2" x 2" x 0.090 wall

10" of 2-1/2" round tubing with 0.250 wall

16" of 2" round tubing with 0.250 wall

4 feet of 2" x 2" x 3/16 thick angle iron

2 feet of 2-1/2" wide by 1/8" thick plate----for casters (your particular casters may need a different size mounting plate). Keep in mind that I welded my casters on.

The 1-3/4" square tubing was $64, the remainder of my materials came from remnants at the steel yard and totaled $22

 

Very nice!

Just a quick question though: Why did you place the angle iron support for the vertical riser under the "horizontal wheel crossmember" as opposed to on top of it? Seems like it would give more support if placed on top. Clear as mud?

 

Joe, that part of the design allows the user to bolt the "horizontal wheel crossmember" to the vertical riser. It makes storage a lot easier. It follows the original Tommy B design, which in my opinion, is stronger this way.

 

thanks for the parts list!!!

may head out next weekend!!!

 

The kid and I built one today in about 4 1/2 hrs. I cut and instructed, he welded away. Tried to teach "square", didn't sink in to well. Took some adjusting for final fit. My only suggestion is to bolt the angle irons to the tub first before welding in the 55.5" crosstube.

 

Thanks for the input Mike. Sounds like a fun project for the kid to learn from. Do you have any pics?

 

Just the one in my build thread. I'm going out to the shop in a little bit so i will take some. I also used smaller steel casters just cause I had them.

 

Here you can see I had him put the center upright on top of the cross piece since I put the bolts towards the outside. I wanted it closer so I just to shorten up the space. Did the same with the back bracket.






This pic just shows I use a tension type pivot. Its 1.250 1144 shaft with 2" DOM .375 wall tubing. I make 1 washer out of the DOM and weld to the shaft. Shaft is countersunk about .120" with a 2" washer with a 1/2" hole. Once set I don't have to loosen them any more. I just rotate and it stays where I stop.




This just shows the smaller casters that leaves me about 3/4" ground clearance.

 

picked up the materials today less nuts and bolts... gonna start on it this weekend!

WOOHOO!!

thanks PieLut

 

You're welcome TexasBlues....take some build pics when you finish.

 

i will if you promise NOT to make fun of the welds...

cant seem to find a drill press (thats affordable) that will take anything larger than a 1/2 bit... if im using 1/2 hdwe, i need 17/32s for the hole right?

maybe i can find a 1/2 bit with one of those new fangled smaller diameter shanks... or a chop saw thats worth a poop... gonna hit the pawn shops tomorrow and this weekend

have to pick up the long pieces tomorrow and maybe the casters too... then that should do it... for the materials anyway

 

Nah...don't need a 17/32" just use a 1/2" bit. You should be able to find a reduced shank drill bit. If you are accurate you could get away with using a hand held drill.
