Frequently Asked Questions
What access does the mill require?
The mill will get through a standard double gate approximately 8 feet wide and is 28 feet in length. However, including the truck towing it, which is about 10 feet long, the total length is about 38 feet. If required the mill can be towed so far and then manually manoeuvred into its final position of operation. The mobile sawmill really is very manoeuverable.
Can the sawmill be used on a bank or slope?
No. The mill has to be set up on relatively flat and level ground for its own stability and to be able to operate properly.
What's the largest piece of wood you can mill?
The mill is designed to cut up to 21 ft in length with a finished maximum width of 24 inches. Large logs can be manually prepared beforehand so they will fit on the mill. Please contact me to discuss your project in more detail if you are unsure.
How much timber can you cut in a day?
This is a common question but the answer is not straightforward. Different timber cuts at different speeds, with soft wood being the quickest (e.g. Douglas Fir) and hard wood the longest (e.g. Oak). There is a difference between straight grained timber and knotty timber, knotty being more awkward and fiddly, and it also depends on the end product; beams convert quicker than, say, planks due to more cuts being required per surface area.
Does the milling operation produce much wastage?
Yes, there are a lot of off cuts which are usually left to the customer's discretion. Clients usually convert it to firewood or ask us to include it in our quote. There is also a fair amount of sawdust produced which is usually put into a neat pile and left to decompose. If you wish it to be removed from site we can include this in our quote.
What happens if you hit a nail or foreign object when milling?
A metal detector is used prior to milling which eliminates some of the risk. However, it is still possible and when metal is hit, the blade must be changed immediately. A charge is made for covering the cost of repairing the blade.
What happens if the mill breaks down whilst working?
The down time is deducted from the day rate on a pro rata basis.
What is done with the timber once it has been milled?
It should be sticked and stacked and put under cover (sticking is when small pieces of wood are inserted between each stacked plank to create spaces for the air to circulate and thereby dry the timber.
How long do we need to wait before we can use the timber?
The timber should be seasoned (allowed to dry out) before use. The time this takes can vary between types of timber but as a general rule of thumb wood dries at a rate of 1" per year. Therefore, if you have 2" thick planks sticked and stacked under cover it will take one year (1" each side). There is no need to do anything during this time; just leave it under cover or in a shed undisturbed.
