1 Ton Long Wheelbase Dually Flatbed Pickup vs Machine Height/Size/Weight
My Responses Firstly, many thanks to all the forum members who took the time to respond. Reading the comments has caused me to think about modifications I hadn't pondered previously. One comment in this thread will lead to an upgrade: installing trailer jacks at all 4 corners of the flatbed...- sae8425

Question – At what machine height/size/weight point would forum members consider a 'stout' 1 Ton flatbed pickup truck inappropriate? Background & Details – Let's leave licensing and registration issues aside in this thread: I'm ONLY interested in the physical aspects of machinery carrying...- sae8425

Carlton 1A Arm Elevating Motor Inoperative - Worth Acquiring Complete Drill for$300
I have the opportunity to acquire a Carlton 1A RAD for almost nothing: half the fuel cost from central WI to western PA. The current owner has said that his fuel cost per run is around $600; so, my acquisition cost would be around $300. However; the arm elevating motor on this... -

VFD Start/Stop Considerations (Limitations?) for a Duplex/Triplex Air Compressor
I am in the process of designing a MUCH better compressed air system that will work within the following constraints – WIDELY varying air consumption requirements: for weeks on end 5 to 15 cfm (typical 'light' shop uses) would more than suffice; then for a day or two I would use...- sae8425

Metal Deck or Wood Deck for Machine Transport
Many thanks to all the forum members who have responded. In decking material preferences, the wood proponents greatly outnumber the metal proponents. However, if items are blocked and secured properly, why should a steel deck be any less suitable than a wood deck? Surely the... -

Metal Deck or Wood Deck for Machine Transport
I need a more capable, multi-purpose, machinery, and mobile equipment transporting system (for my private use). My starting point would be an older, sub-26K lb. GVW single rear axle diesel truck, plus a 30K lb. deck over trailer. Both the truck and trailer would be configured with a... -

Enlarging Bores in Thick Hardened Washers
Once again, many thanks to all the forum members who have replied to my post. The machining methods suggested have been most appreciated. And again I must apologize for not providing enough initial information detail– The ‘Extra Thick’ hardened washers I use are also MUCH larger in... -

Enlarging Bores in Thick Hardened Washers
Many thanks to all the forum members who have replied to my post so far. I will look into all suggested solutions. My apologies for not providing enough initial information (or for not clearly explaining what I need to do) – bad boy (old man)! I need to enlarge the bores of purchased... -

Enlarging Bores in Thick Hardened Washers
I want to upgrade my heavy equipment bolting methodology by incorporating ‘Extra Thick’ Through Hardened washers. I will predominately use these washers in bore sizes from 5/16” to 1-1/2” (8mm to 38mm). These washers are from .125” to .250” (3mm to 6mm) thick. As manufactured, these... -

How High Can I Make my Pole Building?

60-40 balancing - which way if using pony to start?
metalmagpie – After reading your 2nd post more closely I would add the following – The size of your RPC is only of significance IF you know the SIZE and DESIGN of the motors you are powering. Using RPC HP alone as the primary measure of capability is misguided. THERE IS NO...- sae8425

320/400 Amp Supply vs Utility Transformer Size vs Loading vs High Voltage Disturbance
I’m in the process of planning an upgrade of a 100 Amp single phase supply fed by a 17.5 kVA pole mounted transformer for a 320/400 Amp single phase supply with a pad mounted transformer. We live in a rural area where every residence for at least half a mile has its own transformer and the...- sae8425

VFD Size vs Single Phase Supply Transformer Size vs Harmonic Distortion Effects

VFD Size vs Single Phase Supply Transformer Size vs Harmonic Distortion Effects

Lagun Liberty Manual Lathes Opinions
These lathes employ a cogged/toothed belt headstock/gearbox drive (i.e. there are no metal gears outside the headstock housing). This seems to be a rather novel/unique feature for a shop sized lathe. I talked to the importer and they contend that this feature makes these lathes MUCH...
