How many hours would this take?

admin

Hey guys about to quote for some stainless trolleys. Curious how many hours someone would estimate it would take to complete 6 of these. All help would be welcome, essentially its 19 cuts of 10.5 meters of steel. Im only looking for hours it would take no materials. I have an idea but want to make sure im not out of the ball park.Regards Attached Images
Reply:This is highly dependent on what kind of set up you have. do you have a jig? Proper cutting/prep tools? welding process, etc.There are no problems. There are only solutions. It's your duty to determine the right one.Hobart Handler 210Airco 225 Amp MSM Stinger
Reply:4 or 5 hours per unit.  Do they have to be welded out solid?  If so then 6 hours.  By the way, im guessingLast edited by usmcruz; 07-18-2012 at 01:11 PM.
Reply:Cut and make one to figure it out? Would give you a better idea than a guess. And obviously after 1 or 2 they would become a bit easier and faster.Last edited by hammer0419; 07-18-2012 at 02:00 PM.
Reply:1 day to cut the steel, then 6 days to build them.  One dolly per day.  thats how i would bid it.

Reply:I would have to agree with ThorsHammer, take the time, set up a couple of jigs, could save you some serious hours if you have more then one or two to build
Reply:Originally Posted by MondoYou might be able to do them all in 5, maybe even only 4 days.
Reply:MIG or TIG? also, finish quality is going to be a big driver on this project. I would tend to agree with the 1 and 6 time frame
Reply:Time is highly dependent on what fixturing you have. I built my milking parlor (5 stalls, each with two gates) without fixtures or jigs. Lots of measure, tack, and adjust. If I had proper fixturing, it would cut my time in half. If I build another, definitely buying some 3 axis clamps.Lincoln Precision Tig 185Lincoln Power Mig 256Hypertherm PM 45Everlast 140STSmith O/A
Reply:The handle of the trolley is the pain in the arse.   The rest of the structure is simple. The rectangular halo (that has the wheels attached) I would build 12 of them as a rectangle with 45* mitres. The rest of the tubes are straight cut and i'd weld in place upside down on your welding table, except for the connecting bar near the wheels.
Reply:If you directly weld the wheels to the frame as in the sketch, then it shouldn't take long, cause it ain't gonna roll.   Otherwise don't overlook the time to mount the wheels.  Will you directly weld the assembly to the frame or will plate or fasteners be needed.  Drilling stainless could take considerable time without proper setup.  As stated, also don't overlook time to obtain required finish quality.  If grinding is required, the be realistic on how long it takes to grind to required quality.
Reply:Solid bar? tubing? angle? what grade of SS? What cutting processes are available to you? What welding processes are available?Wheels?axles?Warp tolerance?Need more info.Tim Beeker.
Reply:1day for cutting and 6 for welding sounds about right, but what kinda finish is it getting? The finish alone can make or break you. If its a satin finish,  or a straight grain.... etc IMHO the finish is the biggest variable right now. http://www.philswelding.com

Reply:id say a day for cutting and proberly fabericate one and a half in a day . they dont look to be to complex
Reply:i would charge a regular customer of mine 6 hours labor to build one.
Reply:Thanks heaps for the responses guys, sorry it took so long to respond as i didnt have internet connect for a week ( long story). I was thinking about going to bid 4 days to do it, they arnt going to be welded solid at the material is 304 31.75mm x 31.75mm x 2mm. Ill weld captive nuts into the legs so i can bolt on the castors without fear of heat distortion. As for the finish they're wont be any just simply scotch brite the welds. Unfortunately the customers is leaning towards another design which ill post when i commence. I think what i gathered from the posts above is not to rush the quality. So i think ill bump it up to 5 days. Thanks for the insight because i really havent bid for work before.Regards
Reply:How any days. !!!Not much different to Pan racks for Commercial kitchens. Made for 1"sq 316 Box. From cutting to Antinox and buff, 3/4 of a day. For all 6.1/3 day cutting2 1/2 - 3 days welding2/3 -1 day Antinox and buff.How much I would charge them out at has little to do with how long it took me. Anything like that costs big bucks
Reply:16 hrs.  +8 more if you need flush ground welds and a pretty grain finish.  You already have a cad model so comming up with a cut list is trivial.   all square corners = trivial fixturing.
